What are we not paying attention to that might turn out to be major news in a few years?
Many innovations have been promised a long time but have yet to materialize, such as gene therapies, supersonic transport, nanobots that roto-root plaque from our arteries and self-writing software.
On the other hand, who knew 20 years back that today 4.3 billion people on Earth could call one another while walking around? That we would have access to so much of the world's information? Or that three-year-olds could figure out a poke-and-pinch interface on today's computers?
In that context, what are today's weak signals?
Together, let's discuss:
* What domains have been simmering a long time, productively?
* Who is working on a clear breakthrough that is underappreciated?
* What very simple things are bigger than we think? When will we notice?
